Post by Supradupra.com » Fri May 28, 2010 2:51 pm

Hi Folks, met up with Ryan this week to pop the Syvecs EUC in & give it a base map - all went well thus far :D

I thought it was now about time I registered here & post up the restoration / build of my JDM 1jz Aero Limited.

I suspect some of you have found me in the past at http://www.supradupra.com with the galactic class LED infested yUK supra, well, this is it's successor!

The original build thread can be found on the yUK MK3 site HERE.

Obviously some of the points will only be valid for the yUK but, it's a Supra & it's a build so, all is good.

This has been copied from my usual forum so, apologies if some smilies or parts are lost in translation, I make no excuses for humour!!! I will now attempt to post this thread so it reads OK, here goes!

****

The story so far.......

Introduction:

As many of you will know I had a prang in my last Aero & thanks to H&S bu1l**** the vehicle was written off for no good reason - see THIS thread for further details.

Ultimately this lead me to try & find another of these rare beauties which, by some abnormal twist of good luck I managed to do!

The car is a 1991 JDM Aero Limited edition fitted with an auto 1J-GTE power plant.

The car was imported into the country in 2005 has covered around 70,000 miles with a full Jap service history to boot.

The car was standard when I got it with the only mods being fancy wheels, an aftermarket air filter and blitz dump valve - which was not even connected to work.

Here she is before the refurb.

Action plan:

The plan is to refurbish this car from the wheels up. This work will include:
  • Complete underside strip, resealed, waxoiled & restored. Will be forming some rear plastic arch liners too.
  • Complete suspension rebuild front and back, full polly pushings, Tokico TEMS shocks, spax springs, strut braces & anything else which requires replacement during build.
  • Uprated brakes with larger fronts, stainless hoses - investigating kits at present.
  • Swapping the engine to the spare hybrided unit I have here. The aim is for around 450BHP or over if possible and reliable. This will be fitted with larger injectors, induction, MAP, exhaust, Koyo rad Walbro, 2J intercooler kit (allegedly fits) & standalone ECU - currently reseraching systems & pricing up.
  • Manual transmission swap using 1j bellhousing, flywheel, Sports clutch, manual prop & pedal box.
  • Full respray less engine bay, my aim is for the Aston deep grey titainium metalic as used on the DB's etc as this will really bring out the lines of the car. I shall be stripping the car down to no trim & removing bolt on items so they can be sprayed properly. Color coding the side mouldings but keeping the clear part of them unpainted.
  • New front grilles - thinking along the lines of stainless diamond mesh in the 2 small grilles and the main lower intake - sort of XKR style. Thinking the black B pillar external vents may look pretty good in powder coat chrome or brushed steel finish if possible?
  • Chrome alloys - same style as on car now but shinyer lol. will stick to 18" as 19's would dent on the first day out round here!
  • Full LED conversion externally, HID main lights, hidden LED side markers built into side trims.
  • Various internal custom electronics, aiming for a very factory look this time, less xmas tree. Much of the control etc will depend on what standalone ECU I opt for and the controls it requires.
  • Complete ICE installation, music and vision.
  • Interior tart up - tho very little is required as all leather is good with very slight wear and sued just needs a brush up. Would like to look into cost of having dash covered in something like alcantara or sued.


The story so far
: 21/04/09

My write off has been totally stripped to the bone - not a single clip, bung or bolt remained on that vehicle, even body panels have been saved!

Can I just politely ask now, please kids don't deluge me with questions about spare parts at present. As and when parts are sorted I will post up items. Thanks.

These are sad photos but, I wanted to show people the additional bracing clearly visible in the Aero chassis.

Here you can see the additional bracing in the rear arches which also latches into the doors by a bracket when they close. The brace directly below the top shock mount is always present.

Image


And again, at the bottom of the A pillars you can see additional bracing welded behind the kick panels. The sills of the aero cars are also a much heavier grade high strength steel compared to the hard tops which are standard body thickness.

Image


With this shell now gone and boxes of parts at my disposal the strip down of the black car can start.

I have decided to do this in stages:

1)Strip and rebuild the suspension, mod the engine, paint & seal the underside and refit all.

2)MOT and shake down of mechanics, tune.

3)Strip interior completely & remove. De trim the car and get car painted with strict instructions not to over spray the underside!!

4)Put it all back together with custom electronics, ICE and enjoy it!

The reasoning for doing it this way is I feel the car is most susceptible to damage during all the mechanical work so, better to do all that pre painting!


General shot with spare power plant on wheels - This 18 year old virgin is about to have it's undercarriage serviced.

Image


Rear underside stripped down, thanks to not being in the yUK for long the underside is rust free & came apart a dream.

Image

Little tip for emptying & cleaning the fuel tanks without getting covered in the stuff -

Drop tank full, complete with filler neck & electrics.

Tape up the 3 pipes and clean the thing now, wile its sealed up, jet wash, scrubbing brushes whatever, the top will be filthy!

Attach a piece of hose pipe the the outlet nipple - just pushes on. Pop the pipe into a receiving petrol filler or container.

Put some crock clips on the pump power leads - make sure they won't short then, run the thing off a car battery - again keeping sparks away from fuel vapour!!

It just gently empties out the tank to just a few litres. these can then be emptied into a bucket by removing the filler neck - real clean and easy compared to using the drain bung! Leaving the opened tank in direct sunlight for an hour or so will then evaporate any remaining fuel leaving the tank safe and dry.


This tank is in near perfect shape & only requires a little clean up and paint. Walbro needs fitting into here before refitting & will prob clean the sender unit too for good measure.

Image


Like a numpty I forgot to loosen the drive shaft mounting bolts & hub nut while wheels were on, this could have been a problem had I not found a large shelf bracket.

2 holes later & this proved an absolute dream bit of toolage allowing me to lock the drive shafts just like that. Simple solutions are the best!

Image


Got the rear sub frame completely stripped on Sunday down to a giant jigsaw. No busted nuts or bolts, the rear lower cam bolts were the only 2 that gave me any hassle at all but, after a bit of persistence came out no problems. & yes - I have marked parts left and right although, after this the car will be realigned fully.


Behind the stripped sub frame is a complete one just for interest.

Image


Interestingly between the earlier (in bits) and later (behind complete) sub frames I noticed one slight difference.

It seems the rear strut rods on the later car have a definite deliberate bend in them where as the earlier 91 strut bars are completely straight. Why this who knows, possibly the bent one offers a degree of "spring"? Alternatively there was a factory Friday fook up, they were too long so a slight bend was incorporated so they fitted :)

That's it for now, lots of cleaning up and bushings to remove next! Updated then.



Update: 10-05-2009.

So, been a busy week and a bit.

Remember that dirty rear sub frame? Well it's now a rather nice collection of uber clean colour coded chunky bits of metal which, I have to sadly admit, are rather nice just to touch and feel :naughty: Shame they are gonna go back on the underside of the car really!

I have not skimped, every single item, and I mean EVERY single item from the smallest bracket or clip rite up to the fluid line umbilical have been painted in about 5 coats of hammerite.

I am determined for this vehicle not to rust!

The polly bushes are all in and ready to go. I will coat the sub frame with waxoil too during fitting for more rust proofing.

Thought I'd mention this too as, it's not obvious & you'll think your one bush short. One of the bushes on the rear hubs is not a bush at all and is in fact a ball joint. It's item number 42210 HERE All you need to do with this is pull back the rubber and refresh the LM grease inside.

If this ball joint is worn it can cause a "clacking" sound under braking etc.


I will probably offer the sub frame up empty then bolt all the parts back on once it's fixed to the car as it's all jolly easy to get to and means I don't need to wrestle with a huge lump of rather heavy metal!

So, here are all the shiny parts so far:

Image


Sadly, I forgot to put the upper wishbones & all the restored bracketry into this shot, which is a shame. I actually polished the upper wish bones to a bright silver (not mirror tho, that's OTT) and clear coated them.

The fuel tank has had around 6 coats of paint, again, I am determined to rust proof this vehicle as much as possible!

Image

I am just awaiting the Walbro pump for the tank, then it can go back in.

I did get taken in by the choice of paint colours so, red pipes are fuel, yellow are vapour and blue is brake :)


I have put the first coat of under seal on the rear part of the car. going to put a second coat on in places for good measure despite most of it being covered in thick rubber already. I have left the bottom of the wheel well until the fuel tank goes on otherwise I come out from under the car looking like a coal miner!

Image


After the success of my DIY rubber rear arch liners I thought I'd have a go at trying to remould a pair of front wheel arch liners into the rear arches.

This I managed to do with some degree of success. The plastic if vacuum form stuff so, can be reformed with a heat gun and thick gloves.

I have managed to form these into the arches picking up on stock fixing points in the rear arch & only requiring 2 additional ones to be drilled.

This will keep the dirt from being driven into the weak spots of the rear arches.

Image


That's it for now. When my bits arrive from SSI I can fit the walbro and bolt the gas tank back up. Brakes etc are easy stuff. after that the project moves to the front sub frame and engine removal :icon_razz

I am now off to rehab for a few days to get over my solvent abuse problems from all the degreasing and painting!:aigo:

Update; 27-05-09

So, another 2 weeks passed but, had some time to play with the car.

To finish off the preparations of the rear sub frame I had the rear callipers to deal with. Once the 3 layers of paint had been removed (yellow, silver & red) I was absolutely gob smacked by the condition of the callipers underneath.

All I have done to these is paint strip them - that's it! Not a hint of rust! The pistons were all greased up behind the boots so, just pulled out with a pair of snipe nose pliers as a lever - incredible! Always wondered what all the bits said

I had to take a photo just because the condition was so incredible. The fronts are the same.

Image

So, not much needed doing to these at all bar painting and cleaning of some of the components.

This is where my OCD clearly comes out as I set out the parts in a little display ... That's everything you should find on the brakes. Usually the steel shims have dissolved in the yUK thanks to our siht weather and evil salt.

Image

Thehand brake stuff was all in great order so, that's all back in and fitted now. All adjusted up too - all easy stuff.

Image


All suspension members have been fitted now, the car put on it's own axles and the whole lot torqued up correctly. Fook me do these things - particularly the cam bolts, torque up hard. About the hardest an 11 stone stick man can manage in fact!

The suspension really is tight with the full polly kit. You can't budge it when jacked up like you can on the rubbers. Only when the cars weight is on it does the suspension move!
went together a dream tho.

Image

Plastic liners now have fixings as if factory. will finish off the edges later in project. They have cleaned up well tho with various cancer inducing chemicals.

Few shots of the subframe refitted with nice shiny bits: There must be an extra few KG just in paint and wax oil applications!

Image

Image

Image

I personally found the easiest thing to do was to fit the subframe up empty as, it's fairly liftable on your own. Because I'm at home at funny times there tends to be nobody for help so, I have to find ways to do all this one manned if possible.

I managed to fit the diff on my own too by using the grab and roll onto chest method. Wedging my arms against the floor I was then able to lift it into position, hold it there and get the bolts in.

Interestingly that thing weighs 60 odd KG! I had to sit down for some time in a darkened room after refitting the diff and frame!

Just need to fit the fuel pump into tank when customs stop holding us all up & the rear undersides complete.


Next up - the front end. Should start stripping this down, well, in a moment anyway...


Update: 12-06-2009

Thought I'd add a few words and pics quickly this evening before I let my hair down, not that my hair isn't constantly let down - by my face...

Thanks for all your feedback, it's good to share a passion with people, obviously not top much passion, we don;t want our own pandemic!

So, the back is pretty much done bar the gas tank which, with the arrival of my latest toys, shall be this weekend.

My attention has now turned to destroying the front of the car. So far I have stripped the front sub frame down on-vehicle, as this made it far easier than wrestling with it unattached.

Everything came off super easy. Cracked off the cam bolts and the lower wish bones just swung down free, which was a relief.

Everything is in the same good nick as the back of the car.

Image


I just have a couple of bits to disconnect on the engine then, once my friend drops round the crane I can lift it out and get it on the trolley.

The front nose cone parts are so perfect it's untrue, seems a shame to pull them apart but, in the name of restoration I shall be stripping out all the coolers etc and doing things to them.

I would like to fit a shiny new intercooler but, need to check on fitment of 2JZ kits.

Image


I received some nice new parts this week in the form of the Aeromotive regulator, Walbro and SARD injectors - which happily come with replacement plugs for the loom, Cheers Marty.

Since the suspension is in small pieces it seems silly to refit old stuff so, I purchased one of THESE kits from the US. 1 Week later it landed in Farnham.

Now, for some car porn blatantly made to look even sexier with use of pussy..

Image

My pussy can clearly be seen gaping at my nipples, yes, my nipples - grease nipples on the new lower ball joints!

Can't remember the last time I saw such a sensible device on a car ball joint & these are cheap!


Anyway I digress, one other pornographic image which has also crept into Supradupra HQ is this fine craft:

Image

A thing of beauty & I thank Kevin and Sheila very much indeed for this :notworthy:

So that's it for now. Got to cut some more bushes out, uuurgh.



Update 05-07-2009

Have to be honest, with the sun coming out my attention turned to swimming pools and solar water heating recently but, I have managed to do a few things to the car.

Got the Walbro all fitted into the FP assy and back in the tank.

Image


Tank all put back together and refitted back on the car now which is a relief, I kept moving that thing around daily!

Yes, I am sad enough to have re marked the white chalk lines on the rubber cushions as they were new from the factory

Image

Pushing the front suspension bushes out was pretty easy TBH, the top wishbones just popped straight out in the vice.

Image


The lower ones took a little chiselling to push back the metal collars then, with help from Mum, they just pushed out in the vice with a nice healthy crack, we all like a nice healthy crack....

Image

At some point, presumably as a joke, someone filled all the ball joints with poo. This I have now removed and replaced with fresh grease. I also replaced any poor condition rubbers at the same time.

Image

Image

After this they all got cleaned up and painted ready for refitting.

Image

Few more shiny bits. Gave the prop shaft a birthday. Wishbones all painted up and polly bushes fitted ready for installation later on. Everything bagged up and stored now until ready.

Image

My "hover mode" is coming along nicely too

Image

That's it for time being. I am still awaiting the loan of the engine hoist from my friend, once I have this I can pull the engine and remainder of sub frame.

I have pulled the steering rack and am currently attacking that.

Update 11-07-09:

As a continuation of the ongoing refurbishment of my suspension, I wanted to fit poly anti roll bar bushes to the supra.

Now, finding ones for the front was not a problem, they are off the shelf even in this pathetic c U ntry so, I just ordered a set from HERE Job done.

Image


The rears however, seem not to exist as far as I can tell. There are some complete rear anti roll kits which come with their own poly bushes but, I was unable to find any - bushes only listed for the rear bar of the MA/JZA70 chassis - definitely not here in the yUK.

So, what I did was measure the diameter of the rear bar then, took a shot in the dark/educated guess as to which other car may have similar bushings & ordered a set of THESE from a Celica. I know there are several "universal" fit bushes out there however, the Celica ones are considerably cheaper :yes:

Now, as you can see from the pic below, the Celica bushings fit slightly differently compared to the standard Supra rear bushes however, with a small modification to the bracket, the Celica bushes can be made to fit perfectly.

Image

(Top) the standard Supra bushes fit internally to the brackets, held in by the folded part of the clamps where as the the Celica ones are the more "standard" fitment (bottom).

By cutting off the folded part of the rear brackets the Celica bushes fit perfectly to the Supra chassis.

Image

And fitted on the bar they looks factory too - perfect retro-fitment.

Image


So, I'm now happy (figure of speech obviously) I have a full set of poly antiroll bar bushes - woo!

Image

All fitted up to the rear sub frame, pretty colour too :)

Image

Some smug bu9ger will now post a yUK link to somewhere that sells supra rear bushes lol.

Update: 19-08-2009

It's that time again, thought I should update this thread so you knew I wasn't slacking too much!

Due to work load & a ferociously busy social schedule , things have been moving slowly the last few weeks however, progress has been made.

Firstly, this bit had to be unclipped, just disconnect the battery earth lead and your done.....

Image

Had to buy an engine lift for this as, the one I borrowed last time is sadly no longer available but, at least I now have another tool to hand & it folds up nicely to fit in your pocket.

From this exorcise I can confirm my absolute hating for slush boxes has only been compounded. Even after weeks of dripping dry, emptying pipes, removing tubes these things still gush out litres of oil whenever you go near them - totally revolting things to deal with & glad to be shot of it in honesty :yes:

Image

A few more spares :) I could put one front and rear and have a 4WD Supra?

Image

That cleared some handy standing room in the engine bay & allowed me to finally remove the front sub frame.

Image


While the AC system is in small bits I decided to clean the evap core. This gets real dirty thanks to the lack of a particulate filter which then decreases it's efficiency & causes that nasty smell after use from the small potato field laying in the core.

This is what's actually in the evap unit (behind glove box)

Image

You can see here how filthy they get, this is even after being blasted with compressed air. Carol Ann would not be able to find this light.... Film reference joke for the kids, but what?

Image

Several baths later, oven cleaner, bleach, more air, detergent & finally Dettol - this was the result :] After this I straitened out any bent fins with a zip tie - a very dull way to spend an evening & fought off Carol Ann who had now taken much interest in, the now, easy to find light :)

Image


While I was doing that, unbelievably the entire front of the car just fell off :)

Image

Ok, so having done it once I got carried away & have ended up licking the engine bay clean so I can respray it black as the scratches just weren't doing it for me!

Just gotta wash this down, rub down a few bits, body wipe it and spray it over. saved a fortune by buying rattle cans off Ebay instead of halfrauds!!

Image

The front falling off reminds me of this little vid which, personally I think is genius :)

http://www.youtube.com/watch?v=8-QNAwUdHUQ


Also, while the weather has allowed *shocked look* I managed to get these bits scoured, cleaned & painted.

Image


So, things moving on slowly but surely. Off to Amsterdam this weekend so, thet will probably be fairly unproductive me thinks.....

****

Update 02-09-2009

So, having seen ET as a child I found myself mentally scarred for life & as an adult have suddenly found the need to wrap something in polythene sheeting with random tubes flowing from it...

Image

Ok, so this is Supradupra HQ transformed into a Heath Robinson spray chamber in a vain attempt to prevent everything else in the car house being covered in black dust!

Not too much rubbing down to do here I'm happy to say. Just a few areas which either I scratched taking stuff out or rub marks from pipes or wires.

Just sanded down any deep areas then degreased the entire bay & under coated/roughed up.

Image

After much solvent abuse from the spray chamber basically becoming more of a gas chamber lol.

Image

Closure panels also painted as manufacturers never seem to do these - even less so on newer cars made mainly from plastics at the front.

Image

Clear coated a few bits - top firewall & slam panel just to give a smoother finish.

I have no idea what 2-2 means, it was written on the closure panel from the factory so, I just re did it after painting, kinda history type thing I guess / sad gimp!

Image

Overall It's tidied up the engine bay nicely & will be easy to touch up in future when the unavoidable scrapes & marks occur. This is about as far as my limited painting skills will go when it comes to the actual car body!

Now the bay is in this state I can start refitting parts as and when they are reconditioned.

Update: 15-09-2009


Time for another update, not been sitting on my ar5e the last few weeks that's for sure.

Finished off the spraying of the monocot panels. This not only adds rustproofing it also makes things look much tidier when you peer into things.

Image

When you start one of these builds it soon becomes apparent any time scale you had was complete fantasy when you suddenly find just one cooler turns into this many parts!

Image

That was just a start, I reconditioned all the coolers, cleaned, any bent fins straitened out then enamelled.

Image

Bumper & nose cone cross members done.

Image

More bracketry & refurbed plastics than you can shake a stick at & there's still plenty to do!

Image

Refitting of hydraulic lines. As you can see the 4th pipe indicating this car will be fitted with a real gearbox :) I was going to paint these but, when I cleaned them up to find they literally were like new I just didn't have the heart or need to cover them up. They are more stealth this way anyhoo.

Image

Some of the front components trial fitted mainly to get the cooler brackets & clamps all assembled in the correct positions before final installation.

Image

There is a serious amount of really heavy gauge metal in the front of one of these things!

Image

Close up of the finish I'm attempting to achieve. It's no concourse runner that's for sure! I just want it looking as "out of factory" as possible before I use & abuse it come sun, rain or snow.

Image


Got a few more parts through today, mainly new vac lines to replace old rubber ones & the wiring loom stuff.

Need to get onto the new ECU system & make a shopping list for Mr. T as the engine tart up is getting ever closer :yes:

Still some big stuff to recon such as the r154, front brakes & flip up assemblies. As well as a whole load more brackets! :banghead:

Hopefully get the remainder of the underside covered in some new underseal. Waxoil some parts & refit the front suspension members.


WARNING
- Prolonged use of solvent based products and dance music can seriously harm your health & start eating your brain!

Update: 11-10-09

It's that time again, I'm sure you all can't wait for this latest instalment of bracketry photographed in captivity!

First up, I'd like to boast I have now been allowed to upgrade from the "Early learner" pedal set with the large novelty sized speDal pedals, to a full set of adult pedals :)

Image

Ever wondered what was inside one of these? For those of you who still believe in the "pop-up fairies" look away now.

Image

Refurbished along with all the pop-up & headlight gear...Hours of fun for all the family.

Image

Image

Wiper motor & boost pipework got the same treatment. Anyone ever seen that book of boring post cards?....AKhemmm..

Image

The boost pipework photographed here in a secret (accidental) "soft" mode making it look young and beautiful A mode which never seems to be available when the camera is pointed in my direction...

Image


7M against 1J (blue) bell housing. The 1j bell is quite a lot shallower, between 1-2 CM. I saw a magazine once filled with pictures of varying bell housings. All different shapes, sizes & colours. I remember I had to reach quite high to get it off the shelf at the news agents, had an exotic name..

Image

Made this look pretty:

Image

There was some random stuff scrawled on the top of the R154 which I restored for (add attempted reasoning behind this act here)

Some random numbers, some Japanese & what appears to be Klingon - explaining the r154's incredible ability to hide reverse on occasions, this must clearly be a cloaking device, hence the Klingon.

Image


I have spent many hours on my hands and knees pulling apart the chassis loom, cleaning it & recovering it in, well, blue obviously!

Image

Wiper mechanisms refitted after reconditioning. Seriously exciting stuff this....

Image

We have some cruise and brake stuff on this side but, most importantly some clutch hydraulics :yes:

Image

We have some ABS, climate, ignition & wiper stuff on this side.

Image

And yeah, this is what it looks like if you hold the camera somewhere else - wooness!

Image

Next time on Stuey's fascinating photos of random car bits, we shall be mainly focusing on how to remove ones thumb from ones ar5e and actually order a new ECU, the Toyota stuff, the brakes, the steering rack, the engine parts.... Yikes!

****

Update: 09-11-09

Well, not much been happening in a practical way to the car for the last few weeks , mainly thanks to social events filling up all my weekends & work getting in the way any other time!

What has been achieved tho is a little parts shopping & plenty of tech investigation. The best way to sum up this projects progression is to revisit the goals set at the beginning of the build:


Action plan:



* Complete underside strip, resealed, waxoiled & restored. Will be forming some rear plastic arch liners too. Virtually complete, front sub frame needs bolting to car after engine done, replacement PS rack still needs sourcing.

* Complete suspension rebuild front and back, full polly pushings, Tokico TEMS shocks, spax springs, strut braces & anything else which requires replacement during build. Complete.

* Uprated brakes with larger fronts, stainless hoses. Wilwood 4 pots with 330mm disks ready to bolt on when front sub frame goes back. rears complete.

* Swapping the engine to the spare hybrided unit I have here. The aim is for around 450BHP or over if possible and reliable. This will be fitted with larger injectors, induction, MAP, exhaust, Koyo rad Walbro, 2J intercooler kit (allegedly fits) & standalone ECU. Solaris 6GP ordered & paid for along with 3bar MAP sensor, NTK wideband O2, boost control & loom adaptor. The rest of the parts are here & fitted or awaiting fitment with exception of the intercooler which may stay stock unless otherwise required.

Some additional trigger wheels will be required to enable full traction control to function. These should be mountable on the inner CV joint flanges - a company has been contacted regarding these.

* Manual transmission swap using 1j bellhousing, flywheel, Sports clutch, manual prop & pedal box. Pedal box in, piping in, GB ready to bolt in just need to obtain pilot bearing to complete the kit.

* Full respray less engine bay, my aim is for the Aston deep grey titainium metalic as used on the DB's etc as this will really bring out the lines of the car. I shall be stripping the car down to no trim & removing bolt on items so they can be sprayed properly. Color coding the side mouldings but keeping the clear part of them unpainted. Respray will be carried out after mechanical works finished. I got carried away and did the engine bay anyway!

* New front grilles - thinking along the lines of stainless diamond mesh in the 2 small grilles and the main lower intake - sort of XKR style. Thinking the black B pillar external vents may look pretty good in powder coat chrome or brushed steel finish if possible? Investigated custom front grilles & was shocked by the £500 price tag. Further investigation required - no hury.

* Chrome alloys - same style as on car now but shinyer lol. will stick to 18" as 19's would dent on the first day out round here! Back burner till respray unless brakes foul on fronts

* Full LED conversion externally, HID main lights, hidden LED side markers built into side trims. Partially completed to date. Experimenting with products & crafty fitting techniques to install Merc "L" style LED running lights into stock fogs. The Merc style running lights I love, the aldi ones I do not, particularly when you see 507 sets every time you go out on the road YAWN!

* Various internal custom electronics, aiming for a very factory look this time, less xmas tree. Much of the control etc will depend on what standalone ECU I opt for and the controls it requires. Work in progress & will be for ever :) The Solaris will do pretty much anything you can think up so, expect to see some interesting stuff in the future.

* Complete ICE installation, music and vision. Partially complete - back burner as not important.

* Interior tart up - tho very little is required as all leather is good with very slight wear and sued just needs a brush up. Would like to look into cost of having dash covered in something like alcantara or sued. Will be undertaken when stripped for paint.


So that's it for now, just wanted to keep this updated.

Update: 01/01/2010

Happy new year kids, may it be a prosperous & happy one for you all preferably with a long, hot & dry summer too!

Time to update this thread as it's been a while. Obviously christsmess got very much in the way of this project over the last few weeks. That and the fact it's been snowing & freezing cold which makes me less willing to play outside!

Attention has turned to the 1jz engine now & giving it a bit of a face lift.

OK so I got a little more carried away than first planned. This little lot fell off so, I thought I may as well clean it up a bit & service a few items while there.

Image

I'm not going to go mad with this..... No really. It will all be clean but, I'll be keeping much of the alloy natural. Much as paint and powder coat looks very pretty, after a few years it will crack & peel on an engine which, just looks rubbish. Besides, there is something genuine about a clean natural finish part. Obviously I'll be buffing up Adi's polishing work :yes:

The block cleaned down well. At some point in it's life the oil changes were strung out a tad resulting in a burnt oil build up in the valve covers. This is purely cosmetic, inspection of the bearings, filters, oil ways etc shows no problems & all is clean on the feed side of things where it's important. a Bum-O-Scope camera came in very useful for this inspection.

So, introducing a naked 1JZ-GTE:-

Image

Image

Image

The 1J engines are a superbly no nonsense design. all the troublesome bollox fitted to the 7M such as FPU, EGR, MAF, CPS was thrown in the bin & this no nonsense unit was produced.

Toyota went OTT after the 7M gasket issues & made EVERY gasket on this engine metal. The troublesome rubber hoses round the rear of the block have been replaced with all metal construction & the amount of rubber piping is dramatically reduced.

The CPS sensor which was always a nuisance to install on the M has been replaced with 2 fixed hall effect cam sensors & a crank sensor triggered by a wheel on the cam belt pulley - no getting these a tooth out!

After all this it then seems odd Toyota went and plonked an incredibly complex & component heavy Hydraulic cooling fan system on this engine instead of opting for twin electrics?!

On the 17th Dec I sent a parts quote request to Toyota who kindly returned it same day & an order was made for the engine bits.

Image

On the 23rd Dec Xmas came early :)

Image

A friend of mine lent me his powder coating system to do the engine parts. An ebay bargain industrial sized oven has proved most useful for this!

I have had much success with this & it's such a simple process. Only down side is it seems I'm slightly allergic to either the powder or the gases given off by the baking so, I have to do this outside hiding under gazebos!

Image

Image

SARD 540's & stock injectors with new insulators.

Image

One day I'd like to learn how to play this flute. I think it's broken as not so much as a farting noise can be made....

Image

Still not having much luck with the flute..... It's dark outside so, must be yUK time 3pm....

Image

I touched on this in another thread. Toyota revised the 1Jz PCV system a few years into it's life by putting the PCV pick up pipe onto the metal pipe into the front turbo instead of having it connect to the "T" as on the earlier engines.

Image
This image shamelessly stolen from another site - do I care? NO, it's a picture of my sodding engine!! lol.

I believe the reason for this mod was to stop PCV vapour swelling the rubber bellows as below, which would restrict inlet air flow considerably over time.

Image



That's it for this exciting episode. Off now to clean uop & powder coat more brackets - joy :)

Update 24/02/2010

It’s that time again, the continuing voyage of a guy in a workshop with a Supra driven only by the compelling fumes of standard thinners…

So, since the last update I have been working away on getting the engine finished & reloading stuff back into the engine bay.

An assortment of parts have come through keeping royal fail & various other delivery companies in business, these mainly being:


A completely rebuilt PS rack courtesy of Eurorack via CAF, an auto factors down here.

From what I understand this rack has been completely rebuilt with all new seals & hydraulic parts, as well as the actual inner rack being re-chromed. Fingers crossed it will not dribble like it’s owner does. It comes with a 24,000/2 year warranty if not.

Also I took delivery of the Solaris 6GP (now Syvecs) This is a very expensive black box! I also got the 3 bar map (GM style) Wide band O2 sensor & the field harness - which sadly is for a Soarer 1J which would appear to have different plugs to the Supra 1J so, Ryan is sorting out another plug to make up a compatible one.

A few instruments have come through too, new rack bushes, few more gaskets I’d missed from my original shopping list etc etc.

Image

Because I’m a tart & the average temperature in the yUK is below 10’C I have invested in a retro fit kit of full front heated seat elements. These I have on my ST24 & they are great! They have 3 settings & I’ll fab some controls up when I do the control gear for all this stuff. They should make roof off driving more comfortable in the long hot summers we never get here….

Also got a set of rear parking sensors just for the hell of it although, I never use them on the other cars that have them, they can be handy on occasions.

Image



I’ve been powder coating like a freak with all this engine stuff. I know I said I wouldn’t go too mad with the engine but, the aim is as if the car had driven out the showroom so, the project just kind of continued that way.

Just out of interest I thought I’d just brush over how the system works for those who may be interested.
Firstly you clean your part, I also pre bake it to clear off any contaminants, I know some people don’t do this, others do. Then, just like paint, you mask off the areas you don’t want covered with masking tape.

Image

Next, it’s out to the tent with the powder coating gun loaded with your desired colour. The system I have here works off dry, clean compressed air. The powder is very fine & gets agitated & propelled out through a nozzle. In tis nozzle is a metal section charged up to around 50+KV judging by the spark which statically charges the fine dust.

You earth the piece your about to coat & just spray an even coating of the stuff.

Image

Then, it’s carefully off to a pre heated oven at 180’c to bake off. The average time is 10 mins but, this entirely depends on the part – the actual part must be at this temperature for that period for the stuff to cure properly so, you have to be sure the part is up to this.

A sprig of thyme & some red wine, few onions these taste great..

Image

Once done, pull the item out to cool off & remove the masking tape while it’s still warm otherwise the stuff is a PITA to remove! Job done, bare part to finished part in an average of 30 mins.

Image


Out of interest, while I have turbos in bits, here is a comparison of a Hybrid Vs Stock ceramic CT12-A.
Image



So with powder coating in mind, you can see from this lot I have had some really really fascinating weekends…
Image

Image


I revised the throttle body linkage & got shot of all the auto & TRC connections that are superfluous to this engine to tidy the thing up a bit.

Image

The coil on plug spark packs got treated to a high temperature paint as things get a tad toasty in the middle of the engine where they live. Nobody sees these but, I know they are there!

Image

After a few hours of oven cleaner – these cam covers came up like new, the oil from the PCV system really cruds up in here & bakes on behind the baffles. Hard work to shift but, all sorted now. I suspect Adi will only know what these were like before!

Image

And finally the engine loom got reconditioned completely. Broken insulation repaired, busted plugs replaced – Toyota sell the housings still when armed with the parts catalogue, thanks Kai for sending that to me.
A large amount of additional wiring went in here too for additional sensors, individual injector control etc. This I ended up making a small sub loom for due to size. I ended up aluminium foil wrapping the part where it runs over the front cam bearings to protect it from heat & space limitations.

After all that I felt it time to start putting stuff back on the engine.
This is self explanatory really,all went back with new parts where needed & new gaskets.

For interest this is how the 1Jz timing gear is set out. Thanks Mark for tightening my crank with your big tool :)

Image


And now just a bit of engine porn…

Exhaust side with the twin hybrids.

Image

Clutch on ready for box.

Image

Inlet side & plenum – where most of the wizardry happens!

Image

Front ancillary end.

Image


And some general shots while it still looks like new!

Image

Image

Image

Image

Image


Obviously belonging to me this power plant must also have a party trick:

Image

Image


Joy, so now that’s in one bit I have started refitting all the engine bay hydraulic & HVAC pipework. The AC got all new seals & polished ally bits seeming as that’s kind of a theme. Hopefully the engine will drop in soon & I can start on the front sub frame assembly & brakes.

Image

Clearly a few more car house disco evenings to go yet!

Update: 08/03/2010


Only been a couple of weeks since my last load of waffle but, this is a biggy. 6 months after undergoing open heart surgery my supra is making good recovery.

For a start it's front legs are starting to grow back:

Image


The boost valve came in so, I conjured up a mounting bracket/hat shield for it & also got my metalwork tools out to make a stock dump valve blanking plate.

Image

Most importantly of all, with a little physical guidance from my folks, the Supra saw the return of it's heart.

Image

All sat in there looking pretty.

Image


Obviously it does not work yet - it needs a brain first! No use in using mine as it's clearly shot!

Ryan has contacted me to say the correct (fingers crossed) ECU plug is on it's way from the US so, a new field harness can be put together.

As I type this, most of the engine HVAC & hydraulics are connected up ready.

Transmission is on awaiting delivery of Redline MT-90. After ordering it last Monday I can now see why it cost £7 P&P - clearly, still not having arrived a couple of hundred miles from Yorkshire, the package must go via Sydney.... I do find it consistently disappointing how a proper "company" takes 7 times longer to deliver stuff compared to a guy in a bedroom on Ebay. Hmmm.


I can now get down to reinstalling it's front legs & feet & tackling the fitting of the Willwood brakes.

Plenty still to do but, getting the engine in has gained me a whole cubed metre of space in the workshop!

Update: 21/04/2010

Time to update the progress on this build again. Various things moving forward, if it were not for a water pump deciding to spontaneously leak on the shaft seal through lack of use I'd be getting an MOT today instead of stripping out the hydro fan system & timing gear!!!!

This annoys me somewhat as, all this stuff was thoroughly tried & tested before the build to make sure this exact hold up never occurred. Typical Supra & typical personal "luck" - Just shows, even if you take the time to test stuff properly it still screws you over!

Anyway. Expensive day at the local auto factors to say the least! Lots of fluid gone in this, & out, in again, out again.....

Image

Bracketry reconditioned for the front suspension system & additional brackets fabricated for the rear TCS sensors.

Image

managed to get a pair of front ABS sensors mounted to the rear diff utilising stock spare holes in the casing for the traction control rear wheel speed sensing.

The brackets are good and strong, should take the strain of being on the back of a car. They pick up on the blind had bolts on the CV flanges. 6 pulses per rotation. I chose this spot because the sensors have to run within 1mm of the moving parts. This area has no movement suspension wise, has the room required & the tabs act as the trigger wheels.

Image

Cables route up through stock grommets into the trunk - no need to drill holes what so ever for this retrofit.

Image

Dull ass video of the sensors in action.

Modified the front hub dust guards to accept the wilwood brake kit. I did not want to simply cut the whole thing off, it aids cooling, prevents crud being thrown onto disks & is generally supposed to be there!

Stock left, Modded right.

Image

This kit fitted great, no messing. The only thing I could fault was the fitment of the braided hose - it could do with being a few inches longer for proper routing & I would personally say the stock type banjo connection is less susceptible to coming loose over time compared to the hose connections on these which I can see being quite easy to loosen. :yes:

Image

Hose routing using spare ABS sensor cable brackets.

Image


As expected the wheels I had already didn't clear the huge new callipers - not even slightly! These are now on Mark3's car.

Image



This meant I had to stump up for a new set of wheels sooner than wanted but, I had a contingency in place for this as, until all was fitted it was impossible to tell.

I opted for a set of Ultralite GT-2's in 18 x 8.5 & 18 x 9.5 (offset 35, stud pattern 5 x 114.3)

I went for the gunmetal finish as, this will be close to the colour of the respray so, should all match nicely through. Silver seemed to stick out loads against the meteorite grey.

Image

Just to prove it moves under it's own steam, the car stretched it's legs onto the drive, I suspect it was at this point the car saw the state of our roads & decided to pop the water pump shaft seal so it could return to a carpeted workshop! Pussy!

Image

Image

It's funny, I have been so used to the car high up ff the ground I was actually shocked into grinning when I stood at the front of it to find it actually only comes up to just above my knees :) these are so low!

Image



So that's it for now, I am in the process of stripping the front of the engine off to get the water pump out. It's a bit of a PITA.

I will decide upon inspection what to do, there is a seal kit listed for the pump but, it's suitably vague as to weather or not it comes with a shaft seal.

The other option is to bin the complexities & oil filled nastyness of the hydrofan dog/child vaccuuming unit, save the space & fit a 2jz water pump & a pair of electric fans.

In honesty, I a being swayed this way just because it will offer so many service benefits in the future over having to strip out the hydrofan system - which only just fits with a Koyo anyway.


The only other thing that will give some of you a laugh is the way I stitched myself up with the PS system. I could not get this bl00dy thing to bleed, I knew it should self bleed but, nothing, not a dribble.

I bit the bullet & removed the pump only to find I had stitched up myself. On reconditioning I'd inserted a blank plug into the fluid inlet of a precise fit to stop oil pi5sing out. The fit was so good & the time scales between refitting & reconditioning long enough for me to completely miss this bung when refitting! It was this that caused me a days worth of head scratching, being covered in PS fluid & filling the swear box!

More soon.
